* [Bug driver/39851] New: gcc -Q --help=target does not list extensions selected by -march= @ 2009-04-22 14:58 amonakov at gcc dot gnu dot org 2009-04-22 23:29 ` [Bug other/39851] " pinskia at gcc dot gnu dot org 0 siblings, 1 reply; 5+ messages in thread From: amonakov at gcc dot gnu dot org @ 2009-04-22 14:58 UTC (permalink / raw) To: gcc-bugs Even though -march=nocona enables SSE2 and SSE3 extensions, gcc -Q --help=target does not list them as enabled. This may be confusing to the user (see http://gcc.gnu.org/ml/gcc-help/2009-04/msg00293.html ): $ gcc -Q --help=target -march=nocona | grep msse[23] -msse2 [disabled] -msse3 [disabled] -msse[23] would be enabled in gcc/config/i386/i386.c:override_options(), called from toplev.c:process_options(), which is in turn called from do_compile(). OTOH, --help=target is processed in decode_options(), which is executed before do_compile. It would be nice if --help=target processing could see options overridden by target backend. -- Summary: gcc -Q --help=target does not list extensions selected by -march= Product: gcc Version: 4.5.0 Status: UNCONFIRMED Severity: enhancement Priority: P3 Component: driver AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: amonakov at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=39851 ^ permalink raw reply [flat|nested] 5+ messages in thread
